Spontaneous Water Imbibition into Diatomite
Proceedings of SPE Western Regional Meeting, 1998Abstract A systematic experimental investigation of capillary pressure characteristics and fluid flow in diatomite has begun. Using an X-ray CT scanner and a specially constructed imbibition cell, we study spontaneous water imbibition processes in diatomite and for reference Berea sandstone and chalk.

Water imbibition by normal and hard soybeans
Journal of the American Oil Chemists' Society, 1981AbstractBy observing the imbibition of dyed water, soybeans were classified into damaged (break in seed coat), normal and hard beans. Hard soybeans were unique in having a long, variable lag time before start‐ing imbibition, but once water uptake was started, the rate was similar to that of normal beans. Soaking hard beans in methanol or ethanol for 24

Effect of Initial Water Saturation on Spontaneous Water Imbibition
Proceedings of SPE Western Regional/AAPG Pacific Section Joint Meeting, 2002Abstract The effect of initial water saturation on gas recovery by cocurrent spontaneous water imbibition and imbibition rate was investigated both theoretically and experimentally. Equations correlating initial water saturation, gas recovery, imbibition rate, rock/fluid properties, and imbibition time were derived and used to conduct ...

Characterization of Spontaneous Water Imbibition into Gas-Saturated Rocks
Proceedings of SPE/AAPG Western Regional Meeting, 2000Summary A method has been developed to characterize the process of spontaneous water imbibition into gas-saturated rocks. Water relative permeability and capillary pressure can be calculated simultaneously from water imbibition data using this method. A linear relationship between imbibition rate and the reciprocal of the gas recovery by

Capillary Pressure at the Imbibition Front During Water–Oil Counter-Current Spontaneous Imbibition
Transport in Porous Media, 2008Counter-current spontaneous imbibition (COUCSI) in porous media is driven by capillary forces. Capillary action results in a high capillary imbibition pressure at the imbibition front and a low capillary drainage pressure at the outlet face. It is the difference between these two pressures that draws in the wetting phase and pushes out the non-wetting ...

Measuring and Modeling Water Imbibition into Tuff
2013Yucca Mountain (Nevada) is being investigated as a potential site for a high-level-radioactive-waste repository. The site combines a partially saturated hydrologic system and a stratigraphy of fractured, welded and nonwelded tuffs. The long time scale for site hydrologic phenomena makes their direct measurement prohibitive.

A Fractal Model of Production by Spontaneous Water Imbibition
Latin American and Caribbean Petroleum Engineering Conference, 2009Abstract A mathematical model was proposed to predict production in rock by spontaneous imbibition. Heterogeneity of rock represented by fractal dimension was considered. This fractal model predicts a power law relationship between spontaneous imbibition rate and time.

Cotton Fiber Properties and Moisture: Water of Imbibition
Textile Research Journal, 2005Southern Regional Research Center (SRRC) is participating in a multi-year area-of-growth study of selected cotton cultivars. We report here preliminary moisture data (water of imbibition) on the cottons from the 2001 crop year, and compare them to maturity properties determined by image analysis and to micronaire.

Improved Spontaneous Imbibition of Water in Reservoir Chalks
IOR 2009 - 15th European Symposium on Improved Oil Recovery, 2009Alteration of wettability to more water-wet and thereby improvement of spontaneous imbibition of water during sea water injection, has been studied using reservoir core plugs from two fractured chalk fields. Core plugs were prepared by removing easily accessible sulphate. The wettability conditions were characterized using the sulphate wettability test.
